I would gladly kill every tick on Earth and whatever relies on eating them so no human has to lose a kid to this again.
The interplay between different components in natural environments is impossibly complex and we basically always get this wrong. Modern LLMs might be able to surface some likely effects of altering a habitat, but it's also very dependent on humans having already studied it in some capacity, there could be new or subtle second-order (and beyond) effects that we just aren't aware of and AI doesn't have the raw data to infer correctly.
But that's not what the previous poster was talking about. This is not the basis of a food web, that's just a parasitic cul de sac. And there are basically infinite such things in nature.
